. it-know'n that I, GUY (l GRABLE, citizen of the United States,residing at. Berwyn, m the county of Cook and State of Illinois, haveinvented a certain new and useful Imro'vement-"in Vehicle Wheels, ,ofwhich the flowing is a full, clear, concise, and exact description,reference being had to the acw p 'y specification. a o I My inventionrelates to vehicle 'wheels havmg pneumatic tires and has for its objectthe provision of improved means whereby the pneumatic tire to ther withthe demount- 1 able rim holding, t e same may be separably 1 securedabout a fixed wheel rim,

In one aspect, my nvention may be generally described as comprisin awheel, a pneumatic tire carried u on a emountable rim clamping 'or,fastenmg devices distributed about the circumference of the fixed rim,and pnitary mechanism common; to said clam mgdevices, whereby; in oneoperation of t e mechanism, the clamping devices .may be operatedto'secure' thedemountable j rim about the fixedrim, and, inanotheroperation, the' clamping devices may be. op-

erated to release the fastening engagement thedemountable rim and thefixed another as ect, my invention may be described as inc ud' alurality of cams distributed about the ed rim of the wheel, a commonmounting therefor, and means for Be effecting simultaneous movement ofthe cams to bring said calms into and out of looking engagement with thedemountable rim of the pneumatic tire for the; urpose stated In thepreferred embodiment of my invenso tion I employ a ring rotatable withrespect a .to the fixed T1111 and in operative relation to or the camsthat are pivotally mounted upon thefixed rim, a movement of the ring inthe flame of the felly serving to operate the cams,'e1ther tofasten thedemountable rim in position or to'release the t1re structure,

'Uc'cording to the direction of movement ofthe ring. -I desirably"associate with the ring, means for securing purchase thereupon toeffect its movement n the plane of the wheel, which means desirably notonly effects such movement of therin'g, but also'serves to secure thering in the positlon that it iscaused V to assume'when the cams areinlocking rela 5} tion with the demountable rim; To these drawings,forminga part of this for the purpose of more readily ends, I interposea ring-actuating device;

which has purchase upon a portion of the ,wheel structure,preferably'the' fixed rim,v in

engagement with the .ring so thata movement of the actuating'device willeffect the desired movement of the ring with respect to the fixed rimand preferably also tosecure the ring in the position that it has beencaused to' assume in order to 'lock the de-i mountable rim in place. Thering thus constatutes aunitary actuatin mechanism adapted to operatesubstantially simultaneously upon the fastening devices (the cams), thisunitary actuating mechanism desirably including as a component" part themechanism that is inte 'secl between the ringand the balance of t "ewheel structure, securing the desired operation of the ring. t

I will explain 'my i'nve tion'more fully by reference to theaccompanying drawing, s'ho the preferred embodiment thereof, inwhic :1:

The'fixed rim (1 of the wheel may be supportedupon the hub b in anypreferred manner or may be otherwise rigid yrelatedwith the hub.'Assumi-ng that the body of the wheel is mainly of wooden, construction,.I desirably make thefixed-ri m artl offmetal whichmetal part should:pre .erab y be permanently attached to the portion of the wheelstructure surrounded: thereby, said fixed rim preferably includingin itsconstruction an outwardl proyje'cting'flangec along one peripheral ege'thereof which actsas a rim structure-retaining flange, as y willlater a pear. A number of spreading eams d are. distributed about andamounted upon "the fixed rini, the mountingfor-the'cams preferably beingpivptal. The cams'fare; desirably located near the eripheral edge of'the fixed rim opposite to t at edge where'the flange c is disposed,and, intlie preferred embodiment of the invention, the fixed rim isprovid ed with open spacesin which the cams-are adapted to be worked,said cams having formations e that act as does the flange c in retainingthe demountable rim from movement in the direction of the axis of thewheel, the portions 6 therefore being in the nature of flangedprojections upon said cams. The cams are provided with slots f intowhich pins 9 carried upon the actuating ring h, -pro ect. The ring h isadapted to rotate in the plane of the wheel structure and is reventedfrom moving in the direction of t e axis of the wheel by engagementwitlrthevertical faces of the cams d upon one side and an in-'- turnedlip '5 formed upon the fixed rim a upon the other side. v v

By/means of the mechanism so far described, the movement of'the ring itin the plane of the wheel in one direction will rotate able rim fromcreeping in the plane of the wheel. However, in order to guard against"any tendency lot the demountable, r m to creep u on tl iey wheel i'n(the wheel plane, I desirab y provide some sgtitable restraining agencywhich may be i the form of a num-' ber of notches m in the fi jzed rim 0and a 'number ofrcorrespondingly paced lugs, feathers or projections nupon,tl demountable rim, which when the demountable rim is being loeatedupon the fixed rim, are placed in i egis ter with the notches m, so thatwher'nthe demountable rim is in position between the flange formations cand e the demountable, rim is prevented from creeping. As an ele ment oftheeommon actuatingdevicecein;

plemental to the element thereof, I desirably em loy a worm screw 0provided with a suitab e ,wrench-engaging surfaee p and mounted upon theinner peripheral face of' the fixed rim and having engagement'with 55,teeth q edge of reverse movement of said ring.

rovided upon the inner peripheral i516 ring it, wlierebya sufficientturn mg movementof the worm screw in one direction will cause the ring hto'move in the plane of the wheel in onedirection and a reverse movementof the worm will occasion a Th e woim by its construction, serves tohold the ring in theposition to which the worm has adjusted it.

The cams pro desirably so related to the fixed rim that when they aredrawn in, they preferably he within the CUCUDi'iQlGHCG oi the ies thedemountable rim The form of pneumatic tire stuieturc which I have shownis of well known construction, to which, however, .I-do not wish to belimited. ItfisTheld in a demountable rim Z that is rigid and preferablymade of metal and which serves 'to retain the pneumatic inflatable anddeflatable tire portion s,

f whichv may be of any suitable selected construction. The fasteningdevices (the cams) act in the plane .of the Wheel outwardly against ablerim with respectto the fixed rim, reverse movement of the fasteningdevices freeing the demountable rim to permit its ,re-

ture. v

It is not the object of my invention to pro vide means for securing thepneumatic portion of the tire to the rim thereof,'but it is the i objectof my invention 'to provide the improvement described, whereby thepneumatic tire structure as a whole including the demountable rimthereof, may be readily secured to or removed from the fixed rim of thewheel, to which end the demountable rim is a distinctly separatestructure from the fixed rim.

While I have herein shown and partic 'larly described the preferredembodiment o the precise construction shown, as changes, may be madewithout departing from the spirit of ,the invention.-'- I Having thusdescribed 'my invention, I claim as new and desire to-s ec-u're byLetters Patent the following:+
